I second the request and must absolutely disagree with opinion of the affinity team. A lot of it has been mentioned above so I try to summarize my critics. Use Cases -> folders: asymmetric 2-folds, 3-folds, many-folds, altar folds, step folds, … -> large format productions: roll-ups and banners side by side with continuing background (with or w/o spacing) -> magazines and brochures: fold outs, center folds (with and w/o need for continuos page numbering) fold out glossaries and TOCs -> poster series: as we all work on widescreen monitors, designing posters side by side rather than one after each other gives you a better impression of the look of the series @Affinity: sorry, your big-spread-with-many-manual-pages-with-cropmarks idea is not acceptable for professional users. Design-Theoretical Thoughts Why should you care? You must have spent a fortune to develop Affinity Publisher. So you probably may have some believe in the future of print. But what do you expect your users are heading to? From my point, the pressure to be innovative is growing for every print designer. If we sell print projects, we have to compete with the low-cost wide-range fast-delivery advantages of digital media. With new production techniques, exclusive papers, fancy colors, spot + 4c, coatings and finishing, embossing, special foldings, cut-outs, laser-cut contours, metallic colors, hot-foiles and many other things we add something to print digital can't compete with. And one of the easiest and cheapest things from a production perspective is a irregular folding scheme of a printed product. Technical Considerations - Professional PDF files for print require precise PDF/X boxes for automated processing in preprint. By telling the user to create a big spread and place several pages with manual crop marks on it, this won't work. Creating the crop marks by hand and fixing PDF boxes in Acrobat or PitStop takes ages and is error-prone. We might have done this two decades before, but since PDF/X and the PSO are the industry standards we work with, this fumbling has thankfully come to an end. - Some of us even use extra tools like PageControl to extend the functionality of InDesign’s page manager with features like vertical spreads, multiple page sizes, editable page alignments etc. This makes designing complex multi-fold flyers much easier – you consequently design across multiple, precisely positioned art boards while still having the functionality of a DTP application (baseline grid, extended typography features, automation, XML…) rather than a illustration application.
